--head - with update, updates rvm to git head version.
--rubygems - with update, updates rubygems for selected ruby
--default - with 'rvm use X', sets the default ruby for new shells to X.
--debug - Toggle debug mode on for very verbose output.
--trace - Toggle trace mode on to see EVERYTHING rvm is doing.
--force - Force install, removes old install & source before install.
--summary - Used with rubydo to print out a summary of the commands run.
--latest - with gemset --dump skips version strings for latest gem.
--gems - with uninstall/remove removes gems with the interpreter.
--docs - with install, attempt to generate ri after installation.
--reconfigure - Force ./configure on install even if Makefile already exists.
Options
-v|--version - Emit rvm version loaded for current shell
-l|--level - patch level to use with rvm use / install
--prefix - path for all rvm files (~/.rvm/), with trailing slash!
--bin - path for binaries to be placed (~/.rvm/bin/)
-S - Specify a script file to attempt to load and run (rubydo)
-e - Execute code from the command line.
--gems - Used to set the 'gems_flag', use with 'remove' to remove gems
--archive - Used to set the 'archive_flag', use with 'remove' to remove archive
--patch - With MRI Rubies you may specify one or more full paths to patches
for multiple, specify comma separated:
--patch /.../.../a.patch[%prefix],/.../.../.../b.patch
'prefix' is an optional argument, which will be bypassed
to the '-p' argument of the 'patch' command. It is separated
from patch file name with '%' symbol.
-C|--configure - custom configure options. If you need to pass several configure
options then append them comma separated: -C --...,--...,--...

--ree-options - Options passed directly to ree's './installer' on the command line.
--with-rubies - Specifies a string for rvm to attempt to expand for set operations.
Action
(Note that for most actions, 'rvm help action-name' may provide more information.)
* usage - show this usage information
version - show the rvm version installed in rvm_path
use - setup current shell to use a specific ruby version
reload - reload rvm source itself (useful after changing rvm source)
implode - (seppuku) removes the rvm installation completely.
This means everything in $rvm_path (~/.rvm).
This does not touch your profiles, which is why
there is an if around the sourcing scripts/rvm.
update - upgrades rvm to the latest version.
(If you experience bugs try this first with --head)
reset - remove current and stored default & system settings.
(If you experience odd behavior try this second)
info - show the *current* environment information for current ruby
current - print the *current* ruby version and the name of any gemset being used.
debug - show info plus additional information for common issues
install - install one or many ruby versions
